Why do our house cats purr? This is the amazing, never-before-answered question that science has decided to address. And Researchers have raised a surprising hypothesisin A study published October 3 in the journal Current biology. Explanation sequence.

“Pads” in the vocal cords!

the Our domestic cats purr It was therefore a mystery, and would soon be solved. these types of Low frequency pronunciation (between 20 and 30 Hz) We are It is surprising, because it is generally observed in larger animalslike elephants, which also have much longer vocal cords than those of cats.

then How can cats vibrate their vocal cords at such low frequencies? Simply becauseThey will have some kind of “pads” (a bit like under their feet) embedded in the vocal cordsAccording to these scholars. This is amazing A type of fatty tissue in the larynx They will be allowed to purr, for example when we pet them.

How did they arrive at this hypothesis? Simply By studying the throats of 8 deceased domestic cats After a terminal illness (no animals were abused during the experiment).

the BoardsTypes of fibrous tissue masses, which were not previously known, Thus increasing the density of the vocal cords, Which makes it vibrate more slowly :Hence these low-frequency sounds come from, despite the small size of cats compared to other animals.

The results, however, persist To be confirmed by experiments on live catsObviously, it is more controversial… Moreover, there are still other mysteries that need to be clarified: How and why does purring occur if the brain has nothing to do with it? Is it a calming mechanism, a sign of contentment or even affection? He follows…
